Application filed Kay 7, 1917, Serial No. 166,885. Renewed August 8, 1918. Serial No. 248,963.

To all whom-it may concern:

Be it known that I, Baoxo STECHBART, a citizen of the United States of America, and a resident of Chicago, in thecounty of of Illinois, have invented certain new "and useful Improvements in ll'lotion-Picture Machines, of which the following is a specification.

This invention relates to motion picture machines, and more especially to that type of suchmachines in which the cooperating film feeding and reeling mechanisms are compactly arranged within an inclosing casing, commonto both, to afford a self-conand portable exhibiting apparatus. And the present improvement has for its various objects I o. )rovide a structural formation and association of parts wherebv the film feeding mechanism can be locked in an inactive condition during the period in which the rewinding operation onto the delivery exhibition of said locked condition of the film feeding mechanism is maintained until the operator effects a change or shift of the actuating mechanism of the film reels from such rewinding position back to a norreel is effected, after an mal winding condition in which the film is free for a normal intermittent feed past the light aperture of the machine.

To provide a simple and effective holding mechanism common to the locking means of the intermittent film feeding mechanism and, the actuating means of the pair of companion film reels aforesaid, the association being such that as said holding means is released from its holding engagement, the operator can effect the reversal or rengagement of the reel driving means to attain a normal film delivery, and with the attainment of such reversal or reengagement of the reel driving mechanism efi'ect an automatic release of the locking means of the intermittent said.

To provide a simple and efficient automatic connection, whereby the automatic driving mechanism of the film reels, is autoof the picture film baclc film and with which the.

film feeding mechanism afore' matically released from a driven association All as will hereinafter more fully appear.

With an accidental firing of said tilm, the said gate or valve 62 will drop by gravity and close the gap or opening between the rollers 61. as the fire releases the tension normally on the picture film.

65 and 66 designate companion driven pulleys mounted on the before described carrying shafts 11 and 12 of the film reels 13, 14, and operatively connected thereto by pawl and ratchet connections 67, so that positive motion can be imparted to a carrying shaft 11, 12, in one direction only, the particular pulley running idle when rotated in the other direction.

In the structure shown in the drawings. the aforesaid pulleys (35, (it), have a spaced relation longitudinally, in order that the aforesaid endless driving belt 38 in engagement with the aforesaid driving pulley 37 can pass around and beneath the aforesaid driven pulleys 65, 66, to impart simultaneous rotation to said pulleys and in the same direction. 'ith the above described arrangement of parts. a travel of the endless belt 38 in one direction will effect a positive rotation of one film reel in one direction, with the companion film reel running idle, while with a travel of the endless belt 38 in the opposite direction the last men tioned film reel will receive positive rotation, and the first mentioned reel will run idle.

68 designate fixed centering cones on the shaft 11 and 12'aforesaid, adjacent to their journal bearings. And 69 designate adjustable centering cones havin movement on the outer portions of said s rafts, and preferably as integral port-ions of adjusting nuts 70, to properly center and clamp the film reels 13, 14, on their respective carrying shafts 11, 12.

1 designates a tightening roller or drum journaled in the upper end of a carrying frame 72, which is pivoted at its lower end to the frame or standard 8 aforesaid. The" carrying frame 72 is preferably of the curved forni shown, and arranged in an inclined position, and with its roller or drum 71 having bearing against the endless driving belt 38, at a distance away from the point of engagement of said endless belt with the driven pulleys 65, 66 of the reeling mechanism aforesaid."

73 designates a spring associated with the carrying frame 72 aforesaid, and adapted to draw the same away from the tightening engagement of its roller or drum 71, with the endless driving belt 38 aforesaid.

74 designates alink pivoted at its lower end to the carrying frame 7 2 aforesaid, and at its upper end to the lower end of a cornpanion link 7 5, the upper end of which is provided with an enlarged hub 76 having journal bearing on the clutch shaft 30 aforesaid. The companion links 74, 75, constitute atog le formation, which, when forci bly straig tened by means hereinafter described. will cause the tightener roller or drum 71 to bear upon and tighten the end less belt 38 upon its associated belt pulleys aforesaid.

77 designates a horizontally disposed operating rod, the inner end of which is piv-v otally connected to the upper link 7 5 aforesaid, while its outer portion slides in a latch plate 78 on the main casing 1, and is provided with an operating handle or lmob 7 9 for convenient manual operation. The operating rod 77 is formed with a peripheral groove 80 near its outer end for looking engagement with a spring bolt or latch, as follows:

81 designates a vertically sliding latch bolt on the latch plate 78 aforesaid, with a normal tendency under the influence of a spring 82 to engage in the peripheral groove 80 of the aforesaid operating rod 77, to hold the same and associated toggle and belt tightening mechanisms in their active positions.

The present improvement involves as one. of its features of novelty, safety interconnecting means between the intermittent film feeding mechanism and the film reelinlg mechanism, as folloWs:-

83 designates a peripherally notched disk fixed on the carrying shaft 25 of the light shutter 26 heretofore described.

8& designates a sliding bolt adapted for locking engagement in an adjacent peripheral notch of the disk 83 aforesaid, and normally held out of locking engagement with said disk by a spring 85.

86 designates an inclined track or cam rail carried by the operating rod 77 aforesaid, and adapted to move beneath the sliding bolt 84 and lift and hold the same in locking engagement with the notched disk 83, while the said operating rod 7? is in its outward position with its associated belt tightening mechanism in a released condition in which no positive driving connection exists between the endless driving belt 88 and driven pulley 65, 66 of the film reels With the above conditions existing, the machine is in condition for a rewinding by hand, through the instrumentality of a removable hand crank 87 on the carrying shaft 12 of the delivery film reel 14, of the picture film back from the receiving reel 13 onto said delivery reel 14,- after an exhibition has been made of said film and so that the same may be in proper reeled condition for subsequent use.

The safety feature of the above described mechanism, is that the film feeding mechanism of the machine is locked against accidental movement and consequent damage, while a film rewinding operation is taking place, and held locked until the film reeling mechanism is restored to its normal delivery condition.

In the present improvement the aforesaid hub 76 of the toggle link 7 5 is operatively associated with the automatic clutch connection of the clutch carrying shaft 30 heretofore referred to, by a structural formation and association of parts as follows 88 designates a collar fixed on the shaft 30 and providing a guide for a sliding clutch pin 89 adapted for operative engagement in one or the other of a circular cluster of reengagement with operating means as follows 92 designates'a spindle or shaft having a sliding movement in the frame or casing 6 aforesaid, in a plane parallel with the clutch carrying shaft 30, and carrying a yoke 93,

having operative engagement in the aforesaid peripheral groove of the hub of the collar 91 aforesaid.

94 designates a spring associated with the aforesaid spindle or shaft 92, and adapted to yieldingly move the clutching means above described into their engaged condition.

95 designates a collar or button fixed on the end of the spindle or shaft 92, outside the frame or casing 6, and adapted for engagement by operating means as follows 96 designatesa cam plate carried by an outer portion of the hub 76 of the toggle link 75 aforesaid, with the cam portion or inclined end of said cam plate adapted to engage the aforesaid collar or button 95 and move the spindle 92 and associated clutch. ing means into a disengaged condition, when the aforesaid link 7 5 has movement in unison with its companion link 7 f and operating rod 77 to release the tightening mechanism of the endless driving belt 38 previous to the film rewinding operation above described. By means of the automatic mechanism just described, positive rotation of the sprocket drums 32, 33, on the shaft 30 is discontinued, and said sprocket drums are left free to rotate idly with the passing portions of the film with which they are in engagement.

The framing mechanism for effecting the proper adjustment of the picture film in relation to the light passage or aperture of the machine shown in the drawings, forms the subject matter of my companion application for Letters Patent, Serial No. 166,867, filed May 7, 1917, and comprises a detail construction as follows The intermittent film feeding sprocket drum 29 before described is loosely mounted on its carrying shaft 28, so as to be capable of a limited independent slidin and turning ad ustment with relation to said shaft, and said drum is normally. locked to said shaft by inter-engaging detent clutch teeth 97, on the adjacent ends of said drum 29 and of a clutch collar 98 fixed on the shaft 28, as shown more particularly in Fig. 1.7.

memos 99- designntes a spring arranged within an enlarged counterbore of the drum 29 and bearing against an abutment collar 99 on g the, main casing 1, and is provided with a handle or knob 102 for manual operation. In the construction shown, the handle or knob 102 occupies the open cavityof the sunken bushing 101, in the normal condition of the parts, and as illustrated in Fig. 7.

With the above described construction, an outward pull or movement of the knob 102 and shaft 100 will effect a disengagement of the clutch teeth 97, against the yielding stress of the spring99, and in such condition of the parts, the operator can efi'ect an independent turning adjustment of the sprocket drum 29 in one direction or the other to attain a proper framing of the picture film in relation to the light passage or aperture of the machine.

With a view to prevent an excessive turning adjustment of the sprocket drum 29 and a consequent liability to tearing of the picture film, the degree of adjustment is limited by the provision of a pin and elongated recess formation 103 on the. sleeve portions of the sprocket drum 29 and clutch member 97, which is fixed on the shaft 28, aforesaid.-

The lamp house 3 and the associated condenser lens system, shown in the drawings,

constitute the subject matter of my companion application for patent, 7 Serial No. 166,868, filed May 7, 1917, and comprises as follows 3 designates the lamp house or casing of acylindrioal form, supported in an annular bushing 104, attached to the top wall of the main casing 1, with the main portion of said house or casing 3 depending into the interior.

The lens 108 is the secondary lens member of the condenser system of the machine, and owing to its arrangement as above described, it is practical to have it occupy a space immediately back of the film gate aforesaid, and thus aid in the attainment of a compact arrangement of the complete machine.

110 designate a pair of adjustable legs, preferably formed with semi-spherical enlargements 111 on their lower ends, and having movement in a lane at right-angles to the optical aXis and ight passage of the machine. Said legs are guided by guide orifices in the bottom web of the casing 1, and by guide bushings 112 in the front web of said casing, as illustrated in Figs. 1, 2 and 3.

113 designate clamping screws associated with the bushings 112 and adapted to clamp the legs 110 at their required adjustment.

114 designate companion semi-spherical buttons attached to the' aforesaid bottom web of the casing 1 near the rear corners of the same, and adapted to act'as rockers for the casing 1, in the tilting adjustment of the same, and which in the present structure is attained by the adjustment of the legs .110 aforesaid, to properly tilt the easing 1 and the objective 2, so that the picture, projected will be displayed in proper position on the exhibition screen.
